{"product_id":"5-inch-performance-downpipe","title":"5-Inch Performance Downpipe","description":"The Palenon Performance 5-inch downpipe is engineered to unlock the full potential of your B58 Gen 1 \u0026amp; Gen 2 engine.\n\nConstructed with a focus on maximum flow, the downpipe features a 5-inch diameter, making it one of the largest on the market for this engine platform. It offers a smooth transition from 4.5\" to 5\" and then to 4\" to optimize exhaust gas velocity. Buyers can choose between a catless version for unrestricted flow or a high-flow catted option.\n\nThis downpipe is compatible with a wide range of BMW and Toyota Supra models equipped with the B58 engine, including various M340i, M440i, M240i, 540i, and the Toyota Supra 3.0T. The product page mentions that hundreds of these downpipes are in use on newer and older B58 engines, often paired with CEL (Check Engine Light) delete kits. For optimal performance and emissions compliance, consider pairing with a CEL delete kit if choosing the catless version or if your vehicle requires it.","brand":"Palenon Performance","offers":[{"title":"Default Title","offer_id":52689325261112,"sku":"DP-B58-Gen1T2-5CTD","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687491998.webp?v=1784905156","url":"https:\/\/store.motormia.co\/products\/5-inch-performance-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
